Part of the fun of trading-card games like Yu-Gi-Oh! is buying and selling valuable cards in your collection. Rare cards can fetch a good price for the right seller, and even cards that might not be worth a lot can earn some cash when sold in bulk. If you intend to sell your cards, keep them in good shape--storing them in binders rather than playing with them--and don't be cajoled into giving them up for less than they're worth. When you're ready to unload them, a few respectable Internet locations can help you.
The global auction that is eBay makes a great first stop when trying to sell Yu-Gi-Oh! cards. Not only is eBay reputable, it provides safeguards to ensure that a buyer negotiates with you in good faith. eBay also is an excellent spot to check the going rate on Yu-Gi-Oh! cards, giving you an idea of what your collection might be worth. Sell cards in bulk there if you can--a big stack of commons with a few rares or holo cards thrown in to sweeten the pot. Or sell pre-built decks that your buyer can start playing as soon as he receives them.
